Description
技术领域technical field
本发明涉及一种车轮，特别涉及一种低地板转向架车轮。The invention relates to a wheel, in particular to a low-floor bogie wheel.
背景技术Background technique
近些年，关于低地板(车辆地板面距离轨道面在250mm-350mm之间为低地板)轨道车辆的研究和使用有了巨大的进步，低地板轨道车辆的使用是为了改变传统高地板(轻轨车的地板面距离轨道面在800mm-1000mm之间为高地板)所造成的上下车不便与运行和时间延迟的问题。低地板轨道车辆提供给人们更加舒适的乘坐感受，它不需要高的站台，方便残疾人、老年人和小孩上下车，减少对城市景观的冲击。低地板车可以减少换乘时间，提高旅行速度，具有实际的经济应用价值。In recent years, great progress has been made in the research and use of low-floor rail vehicles (the distance between the vehicle floor surface and the track surface is between 250mm-350mm) and the use of rail vehicles. The use of low-floor rail vehicles is to change the traditional high-floor (light rail) The distance between the floor surface of the car and the track surface is between 800mm-1000mm is a high floor), which causes the inconvenience of getting on and off the car and the problems of running and time delay. Low-floor rail vehicles provide people with a more comfortable riding experience. It does not require high platforms, which is convenient for the disabled, the elderly and children to get on and off, and reduces the impact on the urban landscape. The low-floor car can reduce the transfer time, increase the travel speed, and has practical economic application value.
传统的轨道车辆的转向架上左右两个车轮由一根传动车轴固定，牵引电机驱动该传动车轴，从而带动左右两个车轮旋转。100％低地板轨道车辆取消了传动车轴，左右车轮解耦，使其能够独立旋转，这种左右车轮可以相互各自独立地绕车轴旋转的轮对称为独立轮对。The left and right wheels on the bogie of a traditional rail vehicle are fixed by a transmission axle, and the traction motor drives the transmission axle, thereby driving the left and right wheels to rotate. 100% low-floor rail vehicles cancel the transmission axle, and the left and right wheels are decoupled so that they can rotate independently. This kind of wheelset that can rotate around the axle independently of each other is called an independent wheel set.
独立轮对的导向性能差，车轮磨耗较大(尤其容易产生轮缘磨耗)，如果踏面外形设计不当，车辆易出现爬轨而发生安全事故。The guiding performance of the independent wheel set is poor, and the wheel wear is relatively large (especially prone to rim wear). If the tread shape is not designed properly, the vehicle is prone to track climbing and safety accidents.
